Service Description: Connecticut 305(b) Assessed Waters 2010 includes rivers, lakes and estuaries that have been assessed in compliance with Sections 305(b) and 303(d) of the federal Clean Water Act. Section 305(b) of the Clean Water Act requires each state to monitor, assess and report on the quality of its waters relative to attainment of designated uses established by the State's water quality standards. Section 303(d) requires each State to compile a subset of that list identifying only those waters not meeting water quality standards and assign a Total Maximum Daily Load (TMDL) priority ranking to each impaired waterbody. Connecticut 303(d) Impaired Waters 2010 is a subset of Connecticut 305(b) Assessed Waters 2010. If one of the designated uses is categorized as not Fully Supporting the assessed waterbody is considered impaired. This assessment is based on information collected and compiled prior to 2010. It represents conditions at a particular point in time and does not represent current conditions. Depending on the type of waterbody - river, lake, or estuary - this informaiton geographically displays attainment and non-attainment (e.g. full supporting, not supporting, not assessed) for each designated use - aquatic life, marine aquatic life, recreation use, fish consumption, shellfish havesting, and drinking water supply.
